Gaten Matarazzo Diagnosed With Cleidocranial Dysplasia

He opened up about his condition during a 2018 interview on The Doctors, where he shared that he was born without collar bones. “I think what the Duffer brothers, the directors of the show, what they really wanted to do was they really wanted to make sure that each character in the show was unique and they had something that was realistic and personal,” he said in regards to Stranger Things.

When Gaten revealed his condition to the showrunners, they decided to write it into the series. “When they heard that I had the condition… they liked how I told them about that and once I got the part they said they’re going to incorporate that and kind of use it in a realistic way,” he explained. He also mentioned that the directors noticed him stretching and that his shoulders were “touching” when he did it. That is when he announced that he was born without collar bones. Gaten’s character was bullied in the show due to the condition which he was “cool” and “realistic.”

What Is Cleidocranial Dysplasia?

Cleidocranial Dysplasia (CCD) is known as a genetic condition that affects ones teeth and bones, as reported by Johns Hopkins Medicine. The condition is considered rare as it affects one in 1 million people, per the health organization’s website. CCD also affects the skull, face, spine, collarbones and legs. People with CCD can have bones that are “formed differently” or more fragile. Similarly to Gaten’s case, collarbones can also be absent in people with CCD.

There are many treatment options for people with CCD, however, it can vary on a case-by-case basis. Some treatments include: orthopaedic surgery, facial reconstructive and dental procedures.

“Those who suffer from Cleidocranial Dysplasia usually have Supernumerary teeth, which are extra teeth that grow in the gums. I’ve had several surgeries to extract these teeth from within my gums and help expose the teeth that should have already grown in considering my age,” he went on to share. “In this surgery, the team of amazing medical professionals extracted 14 supernumerary teeth and exposed six of my adult teeth.
